212 Messrs. W. K. Parker and T. R. Jones on the 



audessus de Bex ; Placentin?; Bayoune? A small iVMmmM/ma 

 adopted by D^Archiac as a species (Monogr. p. 128, pi. 7. 

 f. 13^-17). 



74. Nummulites Rotula, Defr. 1825. Diet. xxxv. p. 224. 

 Morlaie. A variety of N. l<2vigata, in company with which it 

 occurs. See also D'Archiac and Haime's Monogr. p. 105. 



75. Nummulites scabra. Lam. Diet. xxxv. p. 224. The 

 granulose variety of N. lavigata. Ann. Nat. Hist. ser. 3. v. 

 p. 296, & viii. p. 235. 



76. Nummulites spissa, Defr. 1825. Diet. xxxv. p. 225. 

 Locality unknown. According to D^Archiac and Haime (Mo- 

 nogr. p. 115), this is a young Nummulina perforata, Montf. sp. 



See also Helicites and Lenticulites, for other Nummulites. 



77. There is another iVwrnrnw/ma named specifically by Defrance, 

 in MS., namely N. Lucasana, adopted by D'Archiac ; see D'Ar- 

 chiac's 'Progres de laGeologie,^ 1850, iii. p. 238, and D'Archiac 

 and Haime's ' Monograph,' p. 124. It is included with a granu- 

 late N. Spira under the name N. verrucosa by De Roissy. Ann. 

 Nat. Hist. ser. 3. viii. p. 238. 



78. Another Nummulite, named by Defrance N. nummiformis 

 in Alex. Brongniart's 'Vicentin' (1823), p. 51, was not repro- 

 duced in the Diet. Sc. Nat. It is related to N. complanata, 

 and is named N. Brongniarti by D'Archiac and Haime, ' Mono- 

 graph,' p. 110, reasons for not using the name given by Defrance 

 being advanced at p. 111.

 preceding are Orbiculina adunca, F. & M. sp. and varieties. See 

 Ann. Nat. Hist. ser. 3. v. pp. 180 &c., and Carpenter's 'Intro- 

 duction,' p. 93 &c.

 Zooph. pi. 47. f. 2 (Bl. Actinol. pi. 72. f. 2). Paris ; Hauteville.

 Hist. ser. 3. v. p. 291. 



84. Orbitolites concava, Lam. Diet, xxxvi. p. 295. This is 

 Patellina concava, Lam. sp. In 1860 we referred this and other 

 forms to D'Orbigny's genus Oi-bitolina (Ann. Nat. Hist. ser. 3.
